摘要
Nigakialcohol A (1), as unusual cyclization ionone derivative, together with eight known ones (2-9), were isolated from the leaves of Picrasma quassioides (D. Don) Benn (Simaroubaceae). Their structures were elucidated by extensive spectroscopic analyses and comparison with literature data. Compound 2 showed a weak inhibitory effect on NO production at non-cytotoxic concentration (100 mu M) with inhibitory rate of 59%, and thus it should be regarded as potential anti-inflammatory agents.
